Good catch, thank you!

It is public knowledge that the XCD lenses are manufactured by Nittoh, see for instance this interview with Hasselblad product manager Ove Bengtson at the time of the X1D's announcement:

"The lenses are designed by us and manufactured by Nittoh who have made many great lenses in the past, including the lenses for the X-Pan."

Thanks to this patent request we discover that the detailed design also comes from Nittoh。

Dear Mistral75,

So I know that Nittoh is the manufacturer of current XCD lenses as your mention, I keep attention to their patent application.
